Abstract
Organic metal compounds and organic light-emitting devices employing the same are provided. The organic metal compound has a chemical structure of Formula (I) or Formula (II):In particular, one of the following two conditions (1) and (2) is met:(1) R1 is deuterium or C1-6 deuterated alkyl group, when R3 and R4 are independently hydrogen, halogen, C1-6 alkyl group, C1-6 fluoroalkyl or C3-12 heteroaryl group; and(2) R1 is hydrogen, deuterium, C1-6 alkyl group, C1-6 deuterated alkyl group, C3-12 heteroaryl group, or C6-12 aryl group, when at least one of R3 and R4 is C6-12 aryl group or C6-12 fluoroaryl group.
